1. The combination with a track or crossing member, recessed to seat a removable wearplate, of a wear-plate seated in said recess and engaging a wall thereof both laterally and vertically, and means for maintaining said engagement.

2. The combination with a track or crossing member, provided with a recess or pocket in its upper face, of a wear-plate seated therein and engaging a wall thereof both laterally and vertically, and keys or wedges between the said plate and the opposite wall of said recess.

3. The combination with a track or crossing member, provided with a pocket or recess having an underbeveled wall, of a wear-plate seated in said pocket or recess and having a correspondingly-beveled face and means for securing the engagement of said wall and face.

4. The combination with a track or crossing member, provided with a pocket or recess having an underbeveled wall, of a wear-plate seated in said pocket or recess and having a correspondinglybeveled portion engaging said wall and wedges or keys inserted between the opposite side of said pocket or recess and the adjacent wall of the latter.

5. The combination with a track or crossing member having a pocket therein formed with an underbeveled wall at one side and with an overhanging lip at the opposite side, of a removable wear-plate seated in said pocket and having a beveled portion engaging the said wall and at the opposite side a rib or projection, and locking devices engaging said overhanging lip and the rib or projection, substantially as described.

6. The combination with a track or crossing member having a pocket therein formed at one side with an underbeveled wall, and with a groove or channel at the base of said wall, of a wear-plate seated in said pocket and en-' gaging the said wall, and having a rib or swell which enters the said groove or channel.
